Exactly, Kitty. Like Sea Monkeys.

Us geeks and freaks all know that Superman is fallible to the radiation of Kryptonite - remmants of his home planet Krypton. We know too he cannot see through lead as explained in Superman movies and a billion sea monkey sponsored comics.

Throughout the first 3 movies our favourite super hero gets knocked about by the damn green rocks and rays from evil super computers but he never ever makes some form of protection to save his ass against it. Maybe Supes is just nice but dim.

We know that lead protects him from Kryptonite – when he enters Lex Luthor’s underground lair the rock is hidden in a lead encased box. Superman is unaware of its presence as he cannot see through lead and the rock appears to have no effect on the Man of Steel. It is only when Luthor reveals the content of the box as a bomb and Supes consequently opens the box that he is then affected by the Special K. We can then deduce that lead can also be used as a shield for protection from green death rays and... shit.

Supers could make a shield of lead to defend against looney Luthor types but it would be easily damaged in a fight or light breeze. If you don't see knight armour made of lead so lets assume an implement of some sort such as lead underpants is out.

I have a fix - if Superman ingested lead he would not get sick so I propose for the next Superman movie if they wanna use kryptonite against him he should drink some lead based paint or eat some fishing sinkers so he has high lead levels in his blood. The lead will then protect him from the inside!
